The numbers are fascinating. Or horrifying. Take your pick.

Either way, the Boston Red Sox have been hell on earth for Toronto Blue Jays ace Ricky Romero.

Understand that Romero, through almost four full seasons in the big leagues, has established himself as one of the better young lefthanders in the game.

He went into Thursday's start with a career 40-28 record, 3.76 ERA and WHIP of 1.322. Very acceptable numbers.

But against the Red Sox? Oh-my-goodness.

In 11 career starts against Boston, he was 2-6 with an 8.08 ERA and a WHIP of 2.178. He had managed to stay on the mound for just 52 innings in those games and allowed 47 earned runs. And it's not just a few games that skew the stats. He has been universally awful against them.

In five starts during the 2009 season, he had a 7.66 ERA and the Red Sox had a .371 batting average against him. In four starts during the 2010 season, he had a 7.17 ERA and they hit him at a .322 clip. This year, in his first two starts against Boston, he's lasted a total of just 8 2/3 innings, had an 11.42 ERA and the Red Sox hit .405 against him.
